QNAP ES1686dc-R2-2142IT-96G
The QNAP ES1686dc-R2-2142IT-96G network storage device is designed for storing, managing, and backing up company data in continuous operations. This 3U rack-mounted device uses two active controllers to ensure high availability and reduce service downtime. The design with 16 drive bays accommodates SAS drives for fast access to stored information. The device measures 132 × 483 × 630.6mm and weighs 30.3kg. The system supports advanced RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60 disk configurations for reliable protection of sensitive corporate databases.

- The device includes a total of 16 bays with support for fast SAS drives
- Two active controllers prevent system downtime in case of hardware failure
- The redundant power supply has a total output of 1400W
- The system RAM has a base size of 98304MB
- Read speed of 5773MB/s during file transfers
- Connectivity includes 14 LAN ports
High performance
At the heart of the system are two Intel Xeon D-2142IT processors, each with eight cores running at 1.9GHz. The processor's clock speed increases to 3GHz under load. This hardware configuration uses a 64-bit x86 architecture and an integrated AES-NI encryption engine for secure task processing. This enables the device to smoothly handle a large number of concurrent connections and manage demanding corporate computing operations.
Active controllers
The device uses two independent controllers in an active-active configuration. Data is backed up in real time to protect against sudden information loss. If one controller fails, the other immediately takes over all operations. This means end-user access continues without interruption. Status monitoring is made easy by LED indicators for power, system status, and errors, complemented by a built-in buzzer for warning signals.
Network connectivity
The network interface includes a total of 14 LAN ports for fast communication on the corporate network. The read speed is exactly 5773MB/s when transferring large volumes of data. Files are written to the drives at a speed of 2201MB/s. Each controller has four 10GbE SFP+ ports and three gigabit RJ-45 ports that support Wake on LAN and Jumbo Frame functions. This combination of ports helps manage high network loads.
Memory and SSD cache
The base system memory of 98304MB of DDR4 RAM offers sufficient capacity for running databases. Acceleration via a fast SSD cache significantly shortens file access times. This RAM can be expanded up to 524288MB. A total of eight slots on each controller are available for expansion. The system uses L1 ARC read in RAM, L2 ARC read on SSD, and ZIL write cache on NVRAM with an M.2 SSD module for Copy To Flash.
Virtualisation and server application support
The storage supports a wide range of network services, including a web server, database server, and FTP server. File sharing via SAMBA and HFS protocols simplifies daily collaboration. The system fully integrates iSCSI protocols for efficient disk mapping. Advanced tools for operating system virtualisation are also available.
Redundant power and cooling
The entire system is powered by a redundant power supply with a total output of 1400W, with a typical power consumption of 501W in operating mode. The operating temperature is maintained between 0°C and 40°C. Cooling is provided by hot-swappable fans with speeds of up to 16000 rpm. Hard drives can be replaced without shutting down the device thanks to full support for the hot-swap function.
